208 Observation of the Origin of Varieties. 
So long as it is not certain whether a Linaria vulgaris 
apcloria exists, I propose to call the plants with this power 
provisionally L. vulgaris hemipeloria (Fig. 41). This 
name of course refers both to those plants on which iso- 
lated peloric flowers have been observed, and to their 
offspring. 
Cases of true Pcloria (Fig. 39) are also occasionally 
seen in this country in the wild condition. A few local- 
ities for it are recorded in the Floras. I myself had 
some plants from a spot near Zandvoort in 1874, but 
since then it has not been found there again. Only one 
new locality has since become known to me, and this 
was near Oldenzaal (1896). It is of course not known 
whether the Pcloria occurred spontaneously in these var- 
ious localities and had not been introduced from else- 
where, but its high degree of infertility makes the likeli- 
hood of such an introduction very remote. 
For the purposes of my experiment I transplanted 
some plants from the country into my garden in the 
summer of 1886. I selected plants with occasional pel- 
oric flowers and freed their roots as carefully as possible 
of fragments of roots whose connection with the hemi- 
peloric plants was not absolutely certain. The plants came 
from Gooiland. I also collected, at the same time, the 
Linaria vulgaris with Catacorolla, 1 and obtained the 
three-spurred variety (see 8, p. 87) from DR. WAKKER. 
These three forms flowered together in the following 
summer in my garden. 
In 1888 I sowed the seeds which I had collected in 
1887, to produce the second generation, but the plants 
did not flower till 1889 and again in 1890. In the first 
year a single peloric flower was produced amongst in-
